Leaving Your Vehicle With The Engine Running; Torque Lock - Oldsmobile 1995 Silhouette Owner's Manual

Leaving Your Vehicle With the Engine
Running
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is firmly set before you leave it. After
you've moved the shift lever into the PARK (P)
position, hold the regular brake pedal down. Then, see if
you can move the shift lever away from PARK (P)
without first pulling it toward you.
If you can, it means that the shift lever wasn't fully
locked into PARK (P).
Torque Lock
If you are parking on a hill and you don't shift your
transaxle into PARK (P) properly, the weight
of
the
vehicle may put too much force on the parking pawl in
the transaxle. You may find it difficult to pull the shift
lever out of PARK (P). This is called "torque lock."
To
prevent torque lock, set the parking brake and then shift
into PARK (P) properly before you leave the driver's
seat. To find out how, see "Shifting Into PARK (P)" in
the Index.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If "torque lock" does occur, you may need to have
another vehicle push yours a little uphill to take some of
the pressure from the transaxle, so you can pull the shift
lever out of PARK (P).
